GEORGE B. EVANS, 0F FRESNO, CALIFORNIA.

Application filed March 19,1922. Serial No. 543,945.

To all whom it may concern.:

Be it known that ll, GEORGE R.`EvANs, a

of Fresno, in the county of Fresno and Statie of California, have invented certain new and useful improvements in Air Cool ers, of which the following is a specification.

My invention relates primarily to a system for cooling the air in the rooms of buildings and habitations and for` washing the air synchronously with the cooling thereof and has for its object the provision of suitable means and devices for that purpose which will be cheap and simple in construction 'and operation and which will be of the maximum eiiiciency with the minimum cost of upkeep and operation.

Other objects and advantages will appear hereinafter and, while l have shown and will describe the preferred forni of my invention, it will be understood that l do not limit myself to such preferred form but that various changes and adaptations may be made therein within the scope of the appended claims without departing" from the spirit of my invention. In the drawings, accompanying and forming a part hereof:

Fig. 1 is a top plan, partly brokenaway of my invention.

Fig. 2 is a sideelevation of'Fig. 1, partly in section.

Fig. 3 is an enlarged sectional detail of a ortion of my invention.

eferring to the drawings my device Y comprises a' rectangular box 4 supported at a distance from the floor by legs 5, and being open at the top. Box 4 has its front side open as at 6, and has provided in its rear wall a circular opening 7 in which is revolubly mounted a fan or blower 8 whereby, when said fan or .blower is rotated, a current of air'will be drawn in through opening 7 and forced out through I opening 6. Mounted in box 4to extend vertically are a plurality of tubes or containers 9 formed from plastic material of such nature that they will be porous, preferably clay or concrete, having their upper ends open and having their lower ends closed except at the center where they are rovided with a concentric opening 10.

xtending transversely of and beneath box 4 is a supply pipe 11 the free end of which extends upwardly at one side of Said box so positioned as to pass directly beneath the rows of containers 9 and extending upwardly from these laterals are feeder pipes .15 which pass through' openings 10 in containers 9 and terminate a. short distance above the bottom thereof, a packing washer ,16 of rubber or other suitable material being provided to form watertight joints between said containers and pipes'.

A cover -17 is provided to be detachably mounted upon the upper end of box 4 to enclose the same and prevent the admission of foreign material thereinto.

In the operation of my device the parts will be in the positions shown. Water will be admitted intotank 12 in any suitable manner. lf tank 12 is connected to a water supply system suitable means will be provided to regulate the .heighth of the water in said tank, suchas a float or the like. The water from tank 12 will flow through supply pipe 11, lateral pipes 13 and 14 and feeder pipes 115 into containers 9, it being understood that the heighth of water in said containers will be controlled by the heighth .of water i said tank 12 and thatv therein will be adapted to seep or percolate therethrough and the current of air being forced through box-4 will be purified and cooled through contact with said moisture. llt will be noted that the alternate rows of containers 9 are staggered the pur-` pose of which is to cause said containers to act as batiies thereby causing the air to be thoroughly cooled and washed.

Having described my invention what l claim is:

1. An air cooling device comprising a substantially rectangular box open at the top;

in said box to extend vertically and being open at the top, and closed at the bottom, except at the center thereof; openings in the bottom wall of said box in register with the 'openings in the bottom of said containers;

supply pipes extending upwardly through said last openings into said containers; a tank mounted onvthe side of said box the tops of said containers and said box l ing in the same plane; and a connection rom the bottom of said tank to said supply pipes.

2. An air cooler comprising a substantially rectangular box; legs supporting said box' Vat each of the lower corners thereof; an`

opening in the top of said box; a removable closure for said last opening; a rectangular opening in one of the walls of said box; a circular opening in the opposite wall of said box; an outwardly extending rim sur-V box in'register with .the openings in the' bottoms o said containers; supply pipes ex-` tending upwardly through said last openings into the interior of said containers,\ therel being one pipe for each of said containers' a supply tank mounted on the side wall o n said box at the upper end thereof; a connec' e tion from the bottom of said supply tank to said supply pipes; and meansto rotate said blower.

3. An air cooler comprising a substantially rectangular box open at its upper end; a closure for said upper end; legs sup ortin said boxl at each of the lower corners t ereo openings in opposed walls of said box; a

casing surrounding one of said openings ex` tending outwardly therefrom and terminating in a reduced circular opening; an outwardly extending flange surroundin said opening; a blower revolubly mounted 1n said opening adapted to force air throu .h said box; a plurality of spaced containers mounted at theirlower ends upon the bottom of said box to extend vertically; openings projecting through the bottom of said containers; a fpacking recess in the bottom wall of each o said containers concentric with said o ning, the openings in the bottom wall o said box being in register with the openings in the bottom walls of said containers; a supply pipe projecting throu h said openingsinto said containers; a pac ing-in said packing recesses surrounding said' supply pipes; a tank mounted lupon the outer side of one of the closed walls of said box at the top thereof; a connection from the bottom of said supply tank to-said supply pipes; anda water supply for said sup- Hply tank.

In Witness that I claim the foregoing I have hereunto subscribed my name this 18th day of February 1922.
